  • Step 1.) Card Sharks is a probability game fashioned from the old game show of the same name. First, pick whether you want to use an entire deck, or just one suit. This will change the probabilities in the “hint” section. Then, click how many cards you want to be in the game.
  • Step 2.) Make your “wager” and then choose whether you think the next card will be higher or lower than the previous one. Remember, aces are LOW in this game and you can click “hint” to see the actual probabilities. Try to score as many total points as possible by making good probability decisions.
